We hope you know where exactly your partner was all day yesterday, because if there's one day you should worry about a cheating lover, it was yesterday, July 21st.
According to research carried out by affairs website IllicitEncounters.com, yesterday, also known as 'frisky Friday', sees a surge in sneaky romances due to it being one of the last week's before families fly away on holidays together.
Illicit Encounters found a 20% increase on their website in the beginning of July, and by the time yesterday rolled around it had an increase of a massive 45%.
A spokesperson for IllicitEncounters.com, Christian Grant explained: "While many of us long for the summer - the longer evenings, clear skies and generally upbeat atmosphere - the hidden truth is that it's the season that's ripe for adultery.
"Combine the feeling of a summer's day, the fact that we're spending more of our evenings socialising, and with all of us having plenty more skin on show, and you've got a potent cocktail that lays the foundations for cheating; it's something that even the most loyal among us find hard to resist.
"For adulterers who are already in long-term affairs, the summer poses a different problem. Their children are home from school, and with a summer holiday on the horizon, meeting up with their mistress becomes tricky.
"So, the final week of the summer term sees adulterers meet up for what could be one last fling before September comes around."
